Soft Systems Method Integration with Sustainable Energy Systems Development Using ISO 16355

Dr Kim Stansfield, CEng, QFD Black Belt®, Senior Teaching Fellow, Warwick University WMG, UK; Dr Mike Colechin, Partnership Manager, Energy Technologies Institute, UK; Glenn H Mazur, QFD Red Belt®, Executive Director, QFD Institute, USA.

The Soft Systems Method was developed by Peter Checkland's team at Lancaster University in the 1970s to help analyze complex situations or 'soft problems' where the problem for which a solution is sought is not clearly understood, or for which differences of opinion exist as to the precise nature of the problem. Such a 'soft problem' exists in the development of sustainable (economic and environmental) energy systems. This paper will illustrate how modern QFD methods described in the 'ISO 16355 standard for QFD' have been used in the UK's Energy Technologies Institute to help in the analysis of the 'soft problem' of transition to low-CO2 energy systems. Illustrations will be given on how these methods can be used to establish system specifications and designs.

Using QFD to Design a Smart School Quality Factor Model: Integrating QFD into IoT

Amany Alnahdi, Kent State University, Computer Science Department USA / King Abdul-Aziz University, Jeddah, Saudi Arabia; Austin Melton, Ph.D., Professor, Departments of Computer Science and Mathematical Sciences, Kent State University, USA

The internet of things (IoT) relies on the principle of making the whole much greater than individual things by connecting their data. But how can all these things work together effectively? This question is similar to the question which QFD always asks: What is the voice of the customer (VOC) regarding the important qualities of a product? Our research aims to show the integration of QFD will enhance IoT usefulness. This paper begins with an example of developing smart schools with QFD.

QFD for Testing the Internet of Things (IoT)

Thomas Fehlmann, Ph.D., Senior Researcher, Euro Project Office AG, Switzerland

The theory of Combinatory Logic has a model that is very useful when dealing with unknown cause-and-effect relationships. Combinatory Algebra can be seen as a generalization of QFD as it deals with infinite cause-and-effect relationships and it lays the theoretical foundations for managing complexity in the Internet of Things (IoT). This paper shows the model of combinatory logics and how QFD implements such a model in practice, proposing new approaches based on theory for predicting strange and unforeseeable conditions and how the "things" behave under them.

A Method of Software Requirements Analysis Considering the Requirements Volatility from the Risk Management Point of View

Yunarso Anang, University of Yamanashi, Dept of Computer Science & Engineering JAPAN / Institute of Statistics, Indonesia; Masakazu Takahashi and Yoshimichi Watanabe, Ph.D., University of Yamanashi, Dept of Computer Science & Engineering JAPAN

Due to immature and volatile nature of software specifications, the incremental development cycle such as spiral and agile models, or even the conventional waterfall model, are still inadequate to address the challenge. It is easier to just accept the potential of requirements change as a risk. In this study, we describe a method of software requirements analysis in consideration of the requirements volatility risk. We use QFD as the base method, while we apply R-Map as a tool for risk assessment. We use actual software changes tracking record to obtain the risk of changing, and we evaluate our proposed method by applying the method to a real software product as our case studies.

Keywords: software requirements volatility, risk management, quality function deployment, r-map

Early Requirements Validation by Means of Virtual Prototypes for the QFD Use

Christian Esser M.Sc. and Prof. Dr.-Ing. Robert Refflinghaus, University of Kassel, Dept.of Quality and Process Management, Germany

Understanding requirements as part of proactive quality management is important, as is the need for early requirements validation for product development process. For this, using three dimensional virtual reality (3D VR) early on allows developers to visually illustrate or simulate product features and functions. Integrated into the QFD, it is possible to restructure the requirements at an early stage. Based on clear requirement structures, the results of this proactive quality measure can lead to better product quality..

Using AHP in QFD—The Impact of the New ISO 16355 Standard

Thomas Fehlmann, Ph.D., Senior Consultant, Euro Project Office AG, Switzerland; Glenn Mazur, QFD Red Belt®, Executive Director, QFD Institute / International Academy for Quality, USA

Traditional QFD uses ordinal weights-percentages of a total to describe priorities for customer's needs and technical solution approaches, while AHP (Analytic Hierarchy Process) works with profiles-vectors of unit length one, making it mathematically possible to add, subtract and compare profiles. The ratio method proposed by Dr. Saaty has been a part of Modern QFD for some time, and it is now incorporated in the new ISO standard 16335. Not understanding how to properly apply AHP in QFD, however, could lead to project failures, especially if you are still using the traditional House of Quality (HoQ) matrix. This paper discusses why and how to update the HoQ practice to the new ISO.

New Kano Model / New Product Development & Marketing 2016

Using the New Kano Model: How to Really Excite Your Customers

Harold Ross, QFD Green Belt®, General Motors (ret.), USA

Kano model is well known for its intriguing diagram of 'exciting quality' vs. 'expected quality.' However, it is one of the most misunderstood concept. As one of a few who actually examined the original 1984 research by Noriaki Kano, Ph.D., et.al, the author points out some serious deficiencies in the original Kano model as well as the one commonly practiced in America and elsewhere. He then presents the New Kano Model that offers superior insights on what needs to be done to really build excitements in new product development.

Sustainability Function Deployment (QFD) Applied to Increase Environmental and Social Economic Value Added of Products, Service, and Projects

Juan Manuel García, Founder, Leanradarorg and Corporate EHS Sustainability, Baxter Corporation, USA

Products and services have the objective to increase quality of life, but in some cases the result is a negative impact to the community (environment, society, economy, and health). This can be especially true in rural communities. Using QFD to integrate socioeconomic life cycle assessment (SLCA) in five projects will demonstrate up to three times the economic value added. For three projects, information was collected directly in the communities, using focus groups, surveys and investigation. SLCA was then used to understand impact. Finally, critical functions of the projects, products, and services were determined by applying QFD and SFD. Results were examined for social economic return on investment (SEROI) in order to identify functions and characteristics that can maximize economic value added to existing or future projects, products, or services.

TQM Implementation in China via Practicing QFD

Catherine Y.P. Chan, Ph.D., QFD Black Belt®, president, Hong Kong QFD Association, Hong Kong; Prof. Gail Taylor, Hong Kong Polytechnic University, Hong Kong.

Although TQM was introduced to China in the 1980s, it is only recently that Chinese manufacturers began recognizing its importance, as they face increasing competition from countries that offer even cheaper labor and declining global economy that affects the purchasing powers of their overseas customers. Added to this are Chinese organizational culture and Chinese way of implementing TQM that are not helping. This paper explains why introducing QFD is an essential business strategy for Chinese manufacturers in their pursuit for sustainable success in the global market.

"QFD for Cloud Computing"

By Prof. Dr. Georg Herzwurm and Dipl. Wirt.-Inf. Sixten Schockert, University of Stuttgart, Germany

The introduction of the client-server model in the 80s had a huge impact on the information technology used in manufacturing industry as well as within IT organizations (e.g. concerning the operation and the development of applications). Just like that, cloud computing will have a severe impact on almost all industries. This paper describes how QFD can be used to define specifications for cloud based IT solutions. Starting with the global mega trends, this paper explains the characteristics of cloud computing and their impact on the application of QFD, especially on the collaboration of all involved stakeholders. From this analysis and a conducted case study with a German information technology service provider, the authors derive several recommendations on how to execute QFD for cloud computing.

"Helping Software Engineers Apply QFD Methods"

By Leenah Alrabghi, Ph.D. student, Kent State University USA; Austin Melton, Ph.D., Professor, Departments of Computer Science and Mathematical Sciences, Kent State University, USA

There are many documented benefits of using QFD. The software engineer can use QFD as a framework for activities aimed at improving the quality of software. Since QFD was originally proposed to develop high quality manufactured products, a few considerations must take place before applying it to software development. Based on the waterfall model (four phase model), the researchers of this academic paper point out how QFD tools can be used to benefit software engineers, what features QFD is missing with respect to common software engineering practices, and how QFD can become more applicable to software engineers.

New Kano Model / Designing Exciting Quality  2014

"New Kano Model — How to Really Excite Your Customers"

By Harold Ross,QFD Green Belt®, Director, QFD Institute; General Motors (ret.), USA

Dr. Noriaki Kano developed an interesting approach to classifying quality attributes by determining customer satisfaction with different levels of product features or performance. Results of a unique survey of positive / neutral / negative responses to questions can help developers determine whether a new feature or performance would be an exciter or a basic expectation of the customer. General Motors began using Kano's method some years ago and achieved additional insights by making adaptations of the method. Among these insights included revealing unknown market segments, marketing/advertising content, and clearer performance targets for each segment. This papr discusses details of this as well as a case study for automotive braking systems. This modified approach is now called the New Kano Model and will provide better understanding of the model and implementation.

"Designing Sustainable Products With QFD"

By Dale Roach, QFD Green Belt®, Ph.D., P. Eng., Senior Teaching Associate, University of New Brunswick, Canada

As sustainability is often loosely defined and may be desired but not understood by the customer, QFD is an ideal tool for determining a product’s requirements. Additionally, sustainable products can involve significant deviation from traditional solutions so it is important to incorporate it early in the design process prior to the rapid decrease of design freedom that takes place once design has begun. This paper examines the process of developing sustainable products and proposes a framework for ensuring that sustainability is addressed.

"QFD and Requirements Prioritization: A Survey on Security Requirements for Cloud Computing"

By Prof. Dr. Georg Herzwurm; Norman Pelzl, Dipl.-Wirt.-Inf.; Benedikt Krams, Dipl.-Kfm. (FH), M.Sc. of University of Stuttgart - Chair of Information Systems II (Business Software), Germany.

Prioritization is an essential task within QFD, and QFD is highly suitable for the development of Cloud Computing (CC) applications where non-functional requirements play a main role. Many of them are security requirements, often the main concern for CC investments. This paper introduces the usage of QFD for Cloud Computing (CC). In this research, CC security requirements were prioritized by pairwise comparison, showing that not all security requirements are equally important. With this finding, the appropriate usage of QFD for CC development will be discussed.

"Application of QFD to the Symptom Analysis of Input-device Software Defects"

By Yamamoto Takahiro, Software QA, Wacom Co., Ltd., Japan.

The traditional function/regression tests following the design specification do not adequately ensure software quality, due to the evaluation complexity posed by various input-device software such as USB, wireless communication device, sensor, LCD display technologies, etc. This paper proposes a better method for evaluating and analyzing software defects by correctly assessing the symptoms of original causes of failures and identifying the relationships between the operations and subjects through the use of the function deployment tables and state transition tables. This feeds back not only reliability but also functionality to the quality evaluation.

"Study of Applying QFD to Modularity Strategy"

By Tadao Nakamura, Dassault Systemes K.K., Japan.

Japanese manufactures are excellent at developing integral type products, such as cars and complicated machines that need fine tuning (e.g. Semiconductor manufacturing machines). However, many products are currently shifting toward modular systems, and this is where Japanese manufacturers are weak at establishing logical architectures and rules needed for modularity. This paper defines a better modular product architecture by using QFD to arrange many complex issues such as customer needs, cost, technology, manufacturability, serviceability etc. and simulates them through a series of matrices.

Keynote: "QFD for Membership Organizations — Practicing What We Teach"

By Glenn H. Mazur, QFD Red Belt®, Executive Director - QFD Institute, USA; Academician / Treasurer - International Academy for Quality.

Dr. Armand Feigenbaum, appreciating the power of quality thinking in transforming the post-war economies of Europe and Japan, planted the seeds in 1966 for the International Academy for Quality (IAQ), a membership organization that facilitates an international exchange of information about quality in order to promote quality throughout all nations. The IAQ’s growing membership in developing nations means that member needs have to be periodically assessed and incorporated into future activities, beyond its original missions. Following the footsteps of the QFD founders, late Dr. Shigeru Mizuno and Dr. Yoji Akao, the author (an elected member of IAQ since 2010 and the Secretary and Treasurer since 2013) has proposed to current President Janak Mehta, that QFD be used to reassess current member needs and plan future programs. The study began in 2013 with a survey to members regarding their "likes" and "wishes" about IAQ membership and for suggestions for the future. This paper will explain the QFD process being used for this assessment, including the data from the responses, as well as the results to date and ongoing improvements to the organization.

"Elementary QFD: Using QFD to Assess and Evaluate the Learning Environment of a Private School Library and to Systematically Engage an ISACS Review"

By Ken Mazur, QFD Black Belt®, Japan Business Consultants, Ltd., USA

A Modern Blitz QFD® application in a non-traditional customer/product model – a school. Emerson School is a private school located in Ann Arbor, Michigan, which is in the midst of undergoing a review by The Independent Schools Association of the Central States (ISACS). The project goal was to identify key customers and translate their Voice of Customer as well as ISACS criteria into true customer needs. Often organizations act on a situation without fully determining the true needs of stakeholders that would reveal the important context or unstated factor, leading to inadequate solutions or even exacerbated situations. This occurred several years ago. QFD Gemba study revealed the largest and unexpected hindrances to the current learning environment in the library media center. These observations and customer verbatims were translated into true needs and fully ordered using paired comparisons in the Analytic Hierarchy Process (AHP). Finally, the highest ranking needs were evaluated on a systematic level, addressing potential causes for concern such as difficulties of implementation, perception of teachers and students, as well as resources like cost, time and effort.

"Change Fix Model"

By Karthik Jegannathan and Karthikh Pandian, Cognizant Technologies Solutions (India/USA)

Some of the issues that add complication to IT projects include volatility of customer requirements and assessing risks involving changes. The Change Fix Model aims to improve agility of the estimation by using lean and QFD tools, enabling assessment of the impact of a change into the entire software lifecycle, starting with a regression model for establishing the relationship between impact of change and additional effort for implementing the change. A major player in communications was facing cost and cycle time challenges due to quality and volatality of the requirements. The end users faced issues in the features, and integration suffered many functional defects, as a result. Upon a root cause analysis, management wanted a mechanism to measure the volatality and score the quality of the requirements with respect to the importance of prioritizing and baselining requirement changes in agile as well as a non-agile environments. Using a CTQ drill down tree, which is one of the mechanisms to implement QFD, the paper is the first of its kind to measure the impact of a change by using a regression model.

Political QFD 2012

"QFD and Politics (A Sure Way To Start An Argument)"

By Carey Hepler, QFD Black Belt®, 2010 Akao Prize recipient, Solantic Urgent Care (USA)

First of its kind, this paper examines using QFD in a political campaign. QFD is the art and science of taking the voice of the customer (VOC), and, more specifically, the top needs of the targeted customer segments, into consideration before developing a product or service. Can this technique be applied to a political campaign? This paper addresses this lofty question with the specific steps of using Modern Blitz QFD® tools for an actual election campaign by his wife Ruth Ann for a Florida county judgeship. The primary focus of this paper is to understand how to: 1) select target segments; 2) use the voice (top needs) of the target segment customers to develop the strategy; 3) create messaging; and 4) deploy the messaging to the targeted segments. This presentation will present the QFD analytics and tools used to understand the constituents' VOC and formulate the campaign strategy deployment. Carey’s QFD application is solid and innovative. It deploys downstream using the data to make strategic and operational decisions. For example, what sort of true “customer needs” can be identified from this verbatim voice of voters — “what do you think about the Chick-fil-A case?” and then what kind of a campaign strategy and slogan should be deployed?

"Repertory Grid – Potential for Requirements Management in the Quality Function Deployment - An Example of the German Smartphone Market"

By Dipl.-Ing. Philipp Tursch, Industrial and Systems Engineering Department, Brandenburg University of Technology, Germany; Dipl.-Wirt.Math. Katrin Baumert, Chair of Marketing and Innovation Management, Brandenburg University of Technology Cottbus, Germany; Prof. Dr.-Ing. Ralf Woll, Chair of Quality Management, Cottbus University of Technology, Germany

Integration of cognitive psychology science, the Repertory Grid Technique (RGT), into QFD is proposed. In evaluating quality/performance of a product/service, customers follow unconscious personal perceptions, besides consideration of physical properties such as size, color, functions, etc. It is these unconsciously perceived characteristics that play an important role in the decision making process. Based on the Personal Construct Theory that contends that people experience, organize, and describe their environment in terms of cognitive personal concepts, the RGT was initially used in psychological diagnosis but has evolved to a set of general guidelines used in a wide variety of application domains, including environmental studies, education, healthcare, business, and it can be useful in identification of customer requirements in QFD analysis. Using a case of German smartphone market, this paper introduces RGT and show how it can be used in QFD analysis.

"Implementing Quality Function Deployment to Improve Service Quality and Customer Satisfaction: A Three Stages Empirical Approach in Jordanian Mobile Telecommunication"

By Tasneem Alfalah, Glasgow Caledonian University (UK); Elizabeth Williamson, Ph.D.,Glasgow School for Business and Society, Department of Management, Glasgow Caledonian University (UK); Susan Ogden, Ph.D., Glasgow School for Business and Society, Department of Management, Glasgow Caledonian University (UK)

QFD has had considerable success in companies, specifically in service sector, and therefore has been the subject of many research studies in recent years. The purpose of this study is to develop a QFD model that can be applied to evaluate the extent to improve customer satisfaction in the telecommunications industry in Jordan. This industry is vital to Jordanian economy and has become highly developed in recent years. The study develops a conceptual model that integrates the SERVQUAL Gap model and QFD which would, though identification of attractive attributes, highlight the weaker attributes to be overcome and innovative services to be implemented in the future. The first stage involved designing, administering and analyzing the SERVQUAL framework questionnaire. The study population comprises all Jordanian mobile telecommunication companies (Zain, Orange, and Umniah) located in Amman, the capital of Jordan. There is a gap between expectations and experience in all service quality dimensions. The QFD Model will be used to close these gaps.

"Using QFD to Organize Design for Six Sigma"

By Benson Tendler, VP Quality (ret.), Research In Motion, Canada; Gregory Watson, Business Excellence Solutions, Ltd., Finland; and Camille DeYong, Associate Professor, Oklahoma State University, USA

DFSS tools require organization using Product Line Management methods. QFD provides a means to sequentially develop market features into engineering functions that are specified by quantitative requirements which are testable. Understanding the Voice of the Customer and using the Kano Model to characterize engineering functions that are integrated with QFD can help to provide creative insights. This paper illustrates how to develop and deploy this approach to DFSS using QFD as an organization method and using the Kano Model to focus on the transition of market features into engineering functions.

"QFD Applications for the Board of Directors"

By Gregory H. Watson, chairman, International Academy for Quality; Glenn H. Mazur, QFD Red Belt® and recipient of 1998 Akao Prize® for Excellence, QFD Institute, USA; Yoji Akao, Ph.D., Yamagata University, Japan.

Quality Function Deployment is not just a methodology that is useful for engineering or marketing — it is also helpful for organizing the design and development of policy by the Board of Directors. The International Academy for Quality (IAQ) has been developing the concept of "governance quality" over the past 15 years. Recently, IAQ has published an assessment methodology for Boards of Directors to apply in assessing their level of maturity in application of quality in the practices of their activities. This paper and presentation will extend this work by developing infrastructure for the leadership initiatives of a Board in the encouragement of continuous improvement of the organization from their level of executive oversight. The methodology for developing a strategic approach to quality definition and deployment will be the "Voice of the Customer" as developed using QFD.

Complex Systems / Systems Engineering 2011

"Systems Engineering (SE) and Quality Function Deployment (QFD): A SE Perspective on Opportunities for Complementary Application in the Development of Complex Systems"

By Michael W. Grenn, PhD Candidate, The George Washington University (Deputy Director, DTSA); Shahram Sarkani, Ph.D., P.E., Professor of Engineering Management and Systems Engineering, The George Washington University; Thomas Mazzuchi, D.Sc., Professor of Operations Research, The George Washington University, USA

Basic principles of SE are described with emphasis on the SE process and the challenges associated with development of highly complex systems. SE and QFD are top-down, structured, disciplined and tailorable problem-solving processes for identifying customer-focused system solutions, and both processes typically start with an effort to fully understand customer needs. SE can be generally characterized as a functional architecture-based analysis approach to embed quality requirements into the system, and QFD can be generally characterized as a physical architecture-based analysis approach to embed quality functions into business processes. The different perspectives offer potential for complementary application to improve complex system development. Opportunities for complementary application of SE and QFD in the areas of problem understanding, requirements engineering, quality management, cross-functional teamwork, communication, risk management, value engineering, verification and validation, and integrated life-cycle engineering are summarized. The relationship between SE and QFD is illustrated in some cases using figures and diagrams generally accepted to represent best practices. A generalized method for estimation of system complexity early in SE and QFD process is described and a research framework for retrospective analysis of Department of Defense (DoD) Major Defense Acquisition Programs (MDAPs) and commercial engineering projects is discussed. Hypotheses of the relationship between system complexity, design effort, design review, requirements stability, and program success are suggested to gain further insight into the correlation between SE and QFD (comprehensive, 4-phase model, SE+QFD) design effort and successful development of complex systems.

Dynamic Capability Theory / Kano Model 2011

"Applying Dynamic Capability Theory to Understand the Kano Model for Attractive Quality"

By Ali Masoudi, PostTech, South Korea; Gregory H. Watson, Chairman, IAQ; Camille De Yong, Assistant Professor, Oklahoma State University, USA; Benson Tendler, VP Quality (ret.), RIM, Canada

The concept of Dynamic Capability was proposed by David J. Teece as a means to explain certain phenomena regarding innovation in new product development. The Theory of Attractive Quality developed by Noriaki Kano explains the relationship between functional design capability and customer satisfaction for three functional quality conditions. This paper links these two concepts. A proposed scalar relationship between the Kano functions will be proposed based on the degree of capability or incapability based on the Teece concept of Dynamic capability as a means to better explain the erosion of quality functions over time.

Keywords: Dynamic Capability, Kano model, functional quality, customer satisfaction
